Players must extend their power to survive by hunting and defeating dangerous enemy Guardians! Harvest their glowing energy cores to assimilate their power and increase the size of your ship and stock of weaponry. As a player's ship evolves their world and enemies shrink to insignificance, revealing enemies that were too massive and powerful to see before.

Think you've got it beat? Well think again - endless levels that extend for infinity, an armory of weapons which includes lasers, shields and bombs, and procedurally-generated enemies and environments provide a completely new challenge with every game session. Gamers can battle it out in a variety of modes of play, including Survival Mode, Guardian Mode, Defender and Overkill Mode.
